In recent years Gas Electron Multipliers (GEMs) have proven to be reliable amplification stages at high beam rates, and can be used also in Time Projection Chambers (TPCs). Our group developed a double GEM based, finely segmented pad readout TPC for beam monitoring. The utilized GEMs and the custom-design FPGA data acquisition enables rate capability of 1 MHz for a 10 cm$^{2}$ beam spot while providing excellent track-by-track position and angular information, better than 0.1 mm and 1 mrad respectively. The wide dynamic range of the system enables identification from $^{4}$He up to $^{84}$Kr using ionizaton measurement. The performance of the detector and the read-out was tested at the Institute of Modern Physics, Lanzhou, China, at the RIBLL beamline.
